Begin at the End.
Theravāda — the Way of the Elders — is the oldest surviving record of what the living Buddha actually taught 2,600 years ago. Almost every course starts you at the beginning: precepts, posture, watching the breath. This one starts where the Buddha said the path ends — nirodha , cessation — and works backward. Begin with the end in mind, and every technique on the way makes sense.
Cessation is not blackout and it is not death. In the suttas it is the complete stilling of fabrication — perception and feeling switch off ( saññāvedayitanirodha ), and what remains is what was always underneath the noise. The Elders treated it as a real, attainable, repeatable event with an exact staircase leading to it. That staircase is the jhānas, and the fuel for the climb is not willpower.
This portal grew out of a living teaching: focus on Mettā and everything will expand from there. Mettā is not a warm-up exercise before the "real" meditation. Held as the primary object, it subsumes all mental processes into expansion — first of the heart, then of the whole field of awareness, what other lineages would call the light body. The hindrances don't have to be fought; they dissolve in something larger than they are.
